   int n3=22, n4=88;                //this pair ordered
   order(n1, n2);                   //order each pair of numbers

   return 0;
}
void order(int& numb1, int& numb2)
{
   if(numb1 > numb2)                //if 1st larger than 2nd,
   {
      int temp = numb1;             //swap them
      numb1 = numb2;
      numb2 = temp;
